OBJECTIVETo establish the migraine rheumatism stasis syndrome animal model.

METHODThe rat migraine rheumatism stasis syndrome animal model was established through rheumatism stimulation with manual climate box, 5-HT reduction caused by reserpine and local cerebral vasospasm. General vital signs (activity, weight, eye gum, hair, feeding, excrement), head scratch frequency and image collection were observed to analyze the changes in biological signs of stasis syndrome (tongue image RGB), thrombin and serotonin of model rats.

RESULTThe reserpine group and the reserpine plus rheumatism model group showed significant reduction in blood coagulation time, pain threshold and 5-HT content in blood and brain (P < 0.01); the reserpine plus rheumatism model group showed an increase in eye gum and decreases in activity, feeding, with thin sloppy stool. According to the tough RGB values, the control group showed light red toughs, the reserpine group showed dark purple toughs, the reserpine plus rheumatism model group showed gray toughs, with notable differences in tough RGB values in all three group.

CONCLUSIONThe rheumatism stimulation with manual climate box, 5-HT reduction caused by reserpine and local cerebral vasospasm can be used to induce the migraine rheumatism stasis syndrome animal model, but its modeling assessment method and process shall be further improved.

Objective To study the effect of salidroside (Sal) on learning and memory abilities and expression of p75NTR signal transducers and Aβ in AD rat hippocampus.Methods Totally,ninety-six male SD rats were randomly divided into sham-operation group,model control group,Sal low,medium and high dose group,Hup-A group (16 rats in each group).Except for sham-operation group,AD model in the other group was established by slowly injecting 1μL(10 μg)Aβ1-40 in tobilateral hippocampal CA1 area.Sham-operation group was given the same volume of 0.9％ sodium chloride solution.Sal low,medium and high dose group took orally as early as 24 h postoperatively with salidroside 25,50,100 mg· kg-1 for 21days,while Hup-A group took 50 mg kg-1 of Hup-A orally.The same volume of 0.9％ sodium chloride solution was administrated in shanmoperation group and model control group.After administration,the learning and memory function of rats were tested by Morris water maze.The contents of Aβ in serum and hippacampus were determined by ELISA,and protein expression of p75NTR and p-JNK in the hippocampus of the rats were measured by ELISA.Results Compared with model control group,the latent time in water maze training of Sal low,medium and high dose groups were significantly shortened (P ＜ 0.05 or P ＜ 0.01),the number of times of crossing platform of Sal low,medium and high dose group was significantly increased.The contents of Aβ in the hippocampus and the protein expression levels of p75NTR and p-JNK in the hippocampus of Sal low,medium and high dose group were decreased significantly (P ＜ 0.05,P ＜ 0.01).Conclusion Salidroside has protective effects on learning and memory consolidation of dysmnesia rats caused by Aβ.Its mechanism might be related to inhibition of p75NTR regulation pathways for Aβ,reducing the neurotoxic effect of Aβ,so as to reduce cell apoptosis of hippocampus neuron.

Breast contour deformities, lack of volume and asymmetry are common confronted problems after breast augmentation with implants. These problems can be corrected by using temporary fillers or autologous fat grafts. The purpose of this study was to introduce our experience using long lasting temporary filler (Aquafilling(R)) for the correction of unfavorable results after breast augmentation with silicone implants. Two non-pregnant, non-breastfeeding women unsatisfied with previous breast augmentation with silicone implants were recruited for this study. All procedures were performed under local anesthesia with sedation. Efficacy and safety assessments were carried out at follow-up visits (1, 3, and 6 months). The study showed that Aquafilling(R) could provide satisfactory improvement in breast shape and volume. Also it showed that the corrected volume and shape were lasting without affecting the breasts' original volume. Patients reported high satisfaction as Aquafilling(R) was generally well tolerated with no inflammatory reactions or serious adverse events. We recommend that Aquafilling(R) as a new option for the correction of minor problems after breast augmentation surgery with implants. However, further follow-up studies are required to observe long-term results.

OBJECTIVETo investigate the association of V89L polymorphism of the SRD5A2 gene with the prognostic factors of prostate cancer (PCa).

METHODSWe identified the V89L polymorphic sites of the SRD5A2 gene after Rsa-1 restriction enzyme digestion, observed the distribution of V89L (VV, VL and LL) polymorphism in 112 PCa and 89 benign prostate hyperplasia (BPH) patients, and determined the association of V89L polymorphism with the age, free PSA (fPSA), total PSA (tPSA), fPSA/tPSA ratio, tumor stage and Gleason score of the PCa patients.

RESULTSNo statistically significant differences were found in the V89L polymorphism-induced genetic risk frequencies between the PCa and BPH groups (chi2 = 3. 606, df = 2, P = 0. 165), nor any significant correlation between the genotypes of VV and VL + LL and the differences in the fPSA, tPSA, fPSA/tPSA ratio, tumor stage, Gleason score and age of the PCa patients. VV and VL + LL showed no obvious association with the prognostic factors of PCa.

CONCLUSIONV89L polymorphism is not related with the prognosis of PCa, but may be indirectly associated with its risk.

OBJECTIVETo observe the anti-tumor effect of combination TNF-related apoptosis-inducing ligand (TRAIL) with aspirin on liver cancer cell line, SMMC-7721.

METHODSThe survival fraction of SMMC-7721 cells was measured by MTT assay, apoptosis rate and cell cycle was determined by flow cytometry, and the expression of apoptosis-related gene was identified by western blot.

RESULTSThe survival fraction of SMMC-7721 cells treated with 300 ng/ml TRAIL, 3 mmol/L or 10 mmol/L aspirin alone was 82.76%, 81.34% and 71.29% respectively, and the survival fractions of SMMC-7721 cells treated with TRAIL and 3 mmol/L or 10 mmol/L aspirin were 43.54% and 37.8% respectively. The apoptosis rates of SMMC-7721 cells induced by TRAIL and 3 mmol/L or 10 mmol/L aspirin were higher than that induced by TRAIL or aspirin alone (34.76% and 38.56% vs 21.25%, 1.89% and 6.08%), and G0/G1 arrest was observed under TRAIL and aspirin. The expression of Bcl-2 in SMMC-7721 cells treated by 3 mmol/L or 10 mmol/L aspirin decreased markedly, but no effect on Bax.

CONCLUSIONThe cooperative anti-tumor effect of aspirin and TRAIL may be related to the inhibition of the expression of Bcl-2 by aspirin

Objective To explore a sensitive method and index to evaluate renal functional reserve (RFR) in patients with early diabetic nephropathy (DN) using protein loading-scintirenography.Methods Fifty subjects were studied and divided into 3 groups.Group one (G1) consisted of 14 healthy volunteers;Group two (G2) consisted of 15 patients with type 2 diabetes mellitus (DM) and normoalbuminuria; Group three (G3) consisted of 21 patients with type 2 DM and microalbuminuria.All subjects underwent baseline and protein loading-99 Tcm-DTPA scintirenography within one week.RFR was calculated as the difference between stimulated and baseline glomerular filtration rate (GFR), time of peak ( Tb ), time of half excretion ( C1/2 ), residual rate at 20 min ( C20/b ) .Variance analysis and t-test were used to analyze the group differences.Results ( 1 ) The RFR in terms of GFR had statistical difference between any two groups (t=14.884, 32.180, 16.042, all P＜0.01).After protein-loading, the GFR of G1, G2 and G3 increased 20.1, 10.9 and 2.2 ml·min-1·1.73 m-2 respectively.Therefore, the RFR decreased before microalbuminuria in type 2 DM patients.(2)There was statistical difference between the RFR of G1 and G2 in terms of C1/2 (t = 5.505, P＜0.05 ), and between G1 and G3 ( t = 8.914, P＜0.01 ).(3) There was statistical difference of the RFR in terms of TP between G1 and G3 (t = 5.690, P ＜ 0.01 ).(4) There was statistical difference of the RFR in terms of C20/b between G1 and G3 (t= 4.376, P＜0.05 ).Conclusions 99Tcm-DTPA protein loading-scintirenography is an effective method for measuring RFR to evaluate early DN in type 2 DM patients.

The aim of this study was to investigate features of abdominal earthquake-related crush traumas in comparison with non-earthquake injury. A cross sectional survey was conducted with 51 survivors with abdominal crush injury in the 2008 Sichuan earthquake, and 41 with abdominal non-earthquake injury, undergoing non-enhanced computed tomography (CT) scans, serving as earthquake trauma and control group, respectively. Data were analyzed between groups focusing on CT appearance. We found that injury of abdominal-wall soft tissue and fractures of lumbar vertebrae were more common in earthquake trauma group than in control group (28 vs 13 victims, and 24 vs 9, respectively; all P < 0.05); and fractures were predominantly in transverse process of 1-2 vertebrae among L1-3 vertebrae. Retroperitoneal injury in the kidney occurred more frequently in earthquake trauma group than in control group (29 vs 14 victims, P < 0.05). Abdominal injury in combination with thoracic and pelvic injury occurred more frequently in earthquake trauma group than in control group (43 vs 29 victims, P < 0.05). In conclusion, abdominal earthquake-related crush injury might be characteristic of high incidence in injury of abdominal-wall soft tissue, fractures of lumbar vertebrae in transverse process of 1-2 vertebrae among L1-3 vertebrae, retroperitoneal injury in the kidney, and in combination with injury in the thorax and pelvis.

Objective To analyze the risk factors of socio-demographic and clinical characteristics related to sui?cide risk in misdiagnosed bipolar disorderⅡ(BPⅡ) treated for major depressive disorder. Methods A total of l478 con?secutive major depressive disorder patients were interviewed with the Mini International Neuropsychiatric Interview (MINI) in 13 major mental health centers in China. Of the 1478 patients, 190 patients were diagnosed BPⅡ, who were divided into two groups (nonsuicidal risk and suicidal risk) with the suicidality module of MINI. Logistic regression was performed to evaluate significant risk factors associated with suicide risk in misdiagnosed BPⅡtreated for major depres?sive disorder. Results Of the 190 patients, 116 were in the nonsuicidal risk group and 74 were in the suicidal risk group. In comparison to the nonsuicidal risk group, the suicidal risk group had younger age [(34.45 ± 11.18) vs.(37.23 ± 13.22), P=0.008], earlier age at onset [(26.20 ± 9.16) vs. (30.37 ± 11.59), P=0.007], and more suicidal ideation (82.4%vs. 53.4%, P=0.001). Logistic regression analysis showed that age (OR=0.969,95% CI:0.945~0.993) and depressive epi?sodes with suicidal ideation (OR=4.129,95%CI:2.030~8.397) were significantly associated with suicide risk in patients of misdiagnosed BPⅡtreated for major depressive disorder (P<0.05). Conclusions Younger age, severer suicidal ide?ation may be potential independent risk factors to suicide risk in BPⅡwith misdiagnosed with major depressive disor?der.

This study was aimed to explore whether bortezomib can sensitize HL-60 cells to TNF-related apoptosis-inducing ligand (TRAIL) and to investigate its possible mechanism. The HL-60 cells were treated by different concentrations of TRAIL combined with subtoxic concentration of bortezomib. The proliferative inhibition of treated HL-60 cell was analysed by MTT assay. The cell apoptosis was determined by flow cytometry with Annexin V/PI double staining and the expression of caspase-8 was detected by Western blot. The results showed that the subtoxic concentration of bortezomib combined with 10 ng/ml of TRAIL enhanced apoptosis of HL-60 cells, as compared with TRAIL used alone; the expression of caspase-8 increased correspondingly. It is concluded that subtoxic concentration of bortezomib can sensitize HL-60 cells to TRAIL and its mechanism may be related to upregulation of caspase-8 expression.
